Eagle Chevy Pro Street 383 Rotating Assembly 4140 Crankshaft w/ 4340 I Beam Rods & Flat Top Pistons

Eagle has built a solid reputation for making strong, reliable engine components for performance builds. If you're looking to put together a serious 383 cubic inch stroker for your Chevy, this rotating assembly is a well-built foundation. It's designed for naturally-aspirated racing applications, meaning it's built to handle the demands of the track when you're not using forced induction.

At the heart of this assembly is a forged 4140 steel crankshaft with a 3.750-inch stroke, paired with 6.000-inch long I-beam connecting rods made from tough 4340 steel. These rods come with 7/16-inch ARP 8740 bolts, a strong choice for ensuring they stay securely fastened under high stress. The pistons are forged 4032 aluminum from Mahle, featuring a -5cc flat top design and sized for a 4.030-inch bore. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your engine's specific needs and improve sealing. To top it off, this assembly includes King XP rod and main bearings, known for their durability and performance.

This rotating assembly is a significant step up for anyone rebuilding or stroking a Chevy 350 block to 383 cubic inches. Remember, this assembly is not CARB approved and cannot be shipped to California. You'll want to ensure you have the necessary machine work done, such as balancing the assembly and preparing your block, before installation.
